It must have been very private, or something like that, because they were always all smiles and lovey-dovey, especially toward the end and then, whamo! Or could it have been that katy was a little blindsided by this as well? I wonder if she sensed it was coming or not.

This just makes me think that it was all a showmance. John is trying to show that he has changed and he used his relationship with Katy Perry to show that. Whether she was privy to that or not I am not sure of, she could have been in on it as well. We all know that she benefited from this too.
